Naturally; Additional features of Disclosure Lad will be described below and will be the subject of the claims appended thereto. Brief explanation of the drawings for a detailed understanding of the current statement; Reference should be made to the following detailed description of the preferred embodiment; 5 in combination with accompanying drawing: Fig. 1 is a schematic diagram of an embodiment of a drilling system that may include the Wy communication system of the present Discovery embodiment; Figures 2 and 2b schematically show channels machined in a body with load-bearing section for a drill string according to embodiments of the present disclosure; 0 FIG. 3 schematically shows a functional Ug-channel packaged element of an embodiment of the present detection used in combination with a valve actuation assembly; and Fig. 4 schematically shows a functional Uy-channel packaged element of an embodiment of the present disclosure used in combination with a valve actuation assembly. Detailed Description: 5 The present disclosure provides arrangements and related methods for packaging “Functional Elements.” As used herein, a "functional object" is a physical body or assembly designed to implement one or more of the following

Preset posts are either at the surface or below the blisters. The function that Lal performs can be done in or in response to a command signal. in addition to; A functional medium can be dynamic and move between an inactive state and an active state; Or vice versa. This contrasts with fixed means such as screws; small openings; and other inert structures. The instructions in the present disclosure may be used with any tool or section of a tool that is moved by means of a conveyance in a QB fy borehole. The conveying medium can be Jia rigid carrier jointed tube including wire tube; or a non-rigid carrier such as coiled tubing; drill cable sliding line » z-line; And so on. for convenience only; A drill string will be used as a demonstration transport in the discussion below. With reference tentatively to Figure 1; My hometown is shown schematically for System 10 to build; Performance Record 0 Drilling Completion or repair of a wellbore 12. The system 10 includes a drill string 11 and a bottom hitch assembly (BHA) 20. In one embodiment; It can calls the drill string 11 from a section of solid pipe (eg (JU) joint pipe). The drill pipe string 11 can be rotated by an overhead motor 24 or other suitable rotary power means. In one of the non-exclusive embodiments; BHA includes 20 drill bits 26 steering unit 30 drill motors (40) plunger 5 sensor sub ¢50 bidirectional communication and power module (BCPM) communication and power module 60” and plunger formation evaluation (FE) evaluation 70. In gyal configurations BHA 20 can include active anchors; bottom reamers; sliders; pushers; downflow arresters and so on. During “yall” A drilling fluid flows down an inflow bore of the drill string 11 gang above an annulus formed 0 between the drill string 11 and a wall defining the blister bore 12. With reference to Fig. 2” section 90 of drill string 11 is shown (Fig. 1 ); which can be a drill pipe or any of the components constituting BHA 20 (Fig. 1) or any other section of the drill pipe series 11. Section 90 contains a body 89 with a load bearing section 92 and a flush hole 94 that can be centrally or off-centered.Section 90 has 5 rotors 96 which represent one of the main or three primary axes of the tool.Rotators 96 can be an axis around which section 90 rotates.If section 90 does not rotate; the

Rotary axis 96 may be an axis intersecting section 90. In some embodiments; The rotary axis 96 can be aligned with the fluid flow by extending the flow hole 94. The tool section 90 has an outer surface 104 defined by a diameter. in a specific way; The outer surface extends 104 axially for a defined distance with an uneven diameter. in some embodiments; The outer surface of 104 can be considered as the circumferential surface. as described; The rotary axis 96 is parallel to the outer surface 104. The instructions in the present disclosure allow a functional element to be packed directly into the load-bearing section 92 of a blister bottom assembly or other bit. These filling methods can provide greater flexibility in canal access and maintainability while keeping the 94 flow hole(s) clear. For example; There is no need to reduce the cross sectional flow area of the flow bore 94 0 and not necessarily divert the flow from the central axis of section 90. Referring to Figures 12 and 2b; Channel 100 can be created in the payload section 92 to receive one or more objects. Load Bearing Area 92 means the physical mass that carries and transmits compressive loads; cal) bending and/or torsion across section 90. Conduit 100 can have slot 2 accessible from outside section 90. Specifically; Hole 102 is constructed at least partially 5 to penetrate the outer surface 104 of section 90. It should be noted that the end faces of section 90 are not accessible as they are connected to adjacent tools and are effectively located within the tool tubing string or downhole assembly. In one of the non-exclusive embodiments; Channel 100 can have a circular cross sectional profile. In one of the non-exclusive embodiments; At least ola of the channel length 100 is included or covered by the outer surface 104. In other embodiments also 0 the majority of the channel length 100 is included or covered by the outer surface 104. The Gy channels of the current detection can have different orientations; which are shown in Figures 2-b using channels 110 (100; 120). For ease of explanation, section 90 may be considered to have two non-parallel planes, Jie the horizontal plane 106 and the vertical plane 108, both of which are parallel to the rotary axis 96. 5 Channel 100 is tilted and oriented toward the center of section 90. As used herein, “inclined” means that channel 100 has a longitudinal axis 103 of non-zero slope with respect to

to the horizontal plane 106 but not perpendicular to the rotary axis 96. In other words; The slope is greater than zero and less than ninety degrees. Channel 100 may also be described as oblique and extending approximately radially inward from the outer surface of 104; any; Said channel 100 extends at an angle greater than zero and less than ninety degrees from the outer surface 104. In embodiments” there is at least gia of channel 100 which is inclined at the axial position of hole 102 in body 89. In other words; The slope begins or ends at slot 102. Channel 110 can be offset from vertical plane 108 and extends radially downward in a straight line from slot 112. Similarly to channel 100’ the longitudinal axis 113 (Fig. 12) of channel 110 has a non-parallel component Horizontal 106 (Fig. 2b). Said component 0 is parallel to the vertical plane 108. Channel 120 may be offset from the vertical plane 108 and extend radially downward in a straight line from slot 1122 differently from channels 100 (110). The longitudinal axis 123 of channel 120 contains A non-parallel component to the horizontal plane 106 and a non-parallel component to the vertical plane 8. Another difference is that channel 110 (100) are 'blocked' holes. Channel 5 120 is different in that it extends through the entire section 90 and can have a second hole 2b on the outer surface of 104 as shown in Figure 2b. Additionally, one or more lanes (not shown) can connect to channels 100 110 120. These lanes (not shown) can be used to transport wires; solid components; fluid lines; and so on. To equipment in channels 100 110 120. Be aware that channels Lay for the current detection are subject to different tolerances. Channels can have a non-circular cross-sectional profile (not shown). A channel 130 can extend from a slot 132 formed at the inner surface 105. A dat can also be created at the end face 91 of section 90. Furthermore; The Gy channels for current detection can be nonlinear. (Jal) Channel 134 can be grooved to increase the length available by packing a functional element. 5 Other geometries may also employ a slight deviation from a straight line to have the functional element in close contact with the tool body to produce a prestress on the functional element. Consistent with the invention ;

The channel and the functional element can have non-parallel longitudinal axes along the entire length of the functional element when the functional element is in the channel. Subsequently; The functional element comes into contact with the body; The contact results in a prestress on the functional element. In addition, the channel can include complex geometries such as one or more linear segments and one or more nonlinear segments (eg (Jal) hollow sectors). The same said segments can have different geometries (eg ( JE different slopes and curvatures). It has contours, Jie (al), grooves, recesses, or the like. 0 In some embodiments a functional element can be actively connected to conduit 160 as shown in Fig. 4. A conduit 160 can transfer to the functional element at least one of: (1) energy; (2) signal; (3) fluid; (4) component material. A stream 160 can include media that transmit signals between functional element 146 and a discrete component (not shown). The signal can be data or energy signals. For example “Sa” that the signal carrier is “JS wire; 5 fibers or other solid media that transmit electromagnetic signals; optical signals; or audio signals. The carrier of the Lal signal can be a conduit such as a pipe or a channel that transmits fluid-based pressure signals. Said signals can be used to transmit data. in addition to; JAG can transmit the energy signal in the form of electrical energy or pressurized fluid. The term “actively connected” means that the functional component operates over the link and/or the functional component receives/transmits 0 data-encoded signals over the link. in other incarnations; (Sa) The functional element is standalone. By standalone we mean that the functional element can implement one or more functions without a hot link; as described above it supplies power and/or data. By “aT the functional element performs 5 Autonomously control one or more downhole functions using a power supply and internal controls.

without being bound by any specific manufacturing method; Non-linear or hollow channels can be fabricated using drilling techniques (standard); 5014 (standard); ECM Metal forming, molding or additive manufacturing. Lia can create channels (gaps) using more than one component; For example; mandrel or bushing each containing 72 channels; longitudinally bifurcated Which can form a channel when both pieces are assembled. Referring now to Fig. 3 shows a valve actuation assembly 140 that can be used to control borehole flow. The valve actuation assembly 140 contains a body with a load bearing section 142 defined by an outer surface 144. Channels can be constructed; As discussed above in body 142 to contain a functional element which can serve as a non-exhaustive example

0 is an electro-hydraulic actuator 146. For visualization purposes the electro-hydraulic actuator is shown prior to its installation in the receiving channel. As a non-exhaustive example; The electro-hydraulic actuator can be configured to create an electrical connection (for power and contact) as it slides into the receiver channel. In other embodiments the electrical connection is constructed from small-hole ports 147 after assembly of the electro-hydraulic actuator.

5 with reference to Fig. 4; A section for any instrument is shown below the strut but for simplicity will be referred to as valve actuation assembly 140 shown in Figure 3. A conduit 150 is constructed in body 142 to contain a functional element; (ie electro-hydraulic actuator 146. Channel 150 has a hole 2 machined at the outer surface 144 and extends into the body 142. As described above, channel 150 is in an orientation that causes it to be non-parallel to the rotary axis of the valve actuation assembly

0 140. It should be noted that the actuator 146 is installed in the body 142 in such a way as to allow the possibility of fluid flow through the body 142 through a centrally positioned inflow hole 154. It should be understood that the Uy channels of current detection can be used to populate different types of functional elements. Functional items can include instruments, measuring devices, and other types of electromechanical equipment; electric electronic; hydraulic; or pneumatic. For example

only 5; Said equipment may include signal-responsive actuators; electronics » sensors, batteries; Emitting source of energy (eg (JU acoustic sources and radiation sources); pumps

hydraulic; hydraulic actuators; electromechanical actuators; valves; jie jars sample tanks for storing formation material; which includes corer drums; or fluid tanks; antennas; fluid samplers; means of communication; steering ribs effective stabilizers; And so on. The functional element can be electrically operated; hydraulically or mechanically (Jo) eg; using electricity; fluid pressure compressed springs; and so on) and can be controlled (eg in response to control signals; and/or programmed). Furthermore it"; While the valve actuation assembly has been shown; It should be understood that the functional element can be used with any instrument type below Petition which includes; but not limited to; all kinds of reamers; Fasteners » bore hole gaskets; gaskets (calis) gantry plugs; cull chain valves bypass valves” (rotary) guides” conveyors (ha) 0 pressure test tools die taking tools duee extraction tools core MWD sensor (seismic; impedance, acoustic, (NMR “Lola dad, etc.), pressure gauges, etc. It should be recognized that packing arrangements that use Uy channels for Mall detection provide several advantages over conventional packing arrangements. Yl element can be accessed A functional element is packed into the channel described above without removing the downhole tool.Thus, for example, a functional component can be inserted into the downhole tool 5 after the downhole tool is assembled through the hole of the conduit on the outside of the downhole tool.In addition, the Downhole tool retrieved from the drill hole The operator can easily access the functional component without disturbing the joints connectors or other parts of the downhole tool In other words a downhole HA tool can be retrieved through the channel hole and/or can be inserted Tools or gauges through the channel opening to act on the functional element.Thus, 0 service activities such as maintenance, repair, overhaul, and overhaul operations can be performed relatively quickly due to the fact that non-time-consuming downhole tool removal is required. in addition to; As previously noted; The functional elements are packed in such a way as not to impede the flow of drilling fluid through the center flow hole (eg flow hole 94 shown in Figure 2) for drill string 11 (Figure 1). While the foregoing disclosure relates to specific embodiments of the disclosure, it will be clear to those of skill in Domain 5 Numerous modifications All variations are intended to fall within the scope of the claims appended to the previous disclosure.
